基坑工程在建设的过程中主要包含基坑支护体系的设计、施工以及土方的开挖施工,是一项具综合性非常强的系统性工程,在施工的过程中具有非常强的区域性,基坑施工中支护体系所需要承受的土压力又具有非常强的时空效应。通常情况下,基坑支护都是临时进行建设的,地下室主体在进行施工的过程中,基坑支护体系是需要完成的任务,同永久性结构的工程相比临时施工结构的安全储备相对比较小,因为施工的安全储备比较小,所以,在施工的过程中具有非常大的风险。
During the construction process, the foundation pit project mainly includes the design and construction of foundation pit support system and excavation of earthwork. It is a very systematic project with very strong comprehensiveness and has a very strong regionality in the construction process , The earth pressure which the supporting system in foundation pit construction needs to bear also has very strong space-time effect. Under normal circumstances, the foundation pit support are temporary construction, the basement in the construction process, the pit support system is the task to be completed, compared with the permanent structure of the temporary construction of the safety reserve relative to Is relatively small, because of the relatively small safety reserve of construction, so there is a very big risk in the construction process.
